i have a 1971 honda cb750 and it has a problem. in high rpms it misses and cuts out. i tested it with a timing light and the number 3 cylinder doesnt fire all the time. i replaced spark plugs, points and coils and i cant figure out what is goin on. any suggestions will help
thanks

I have a question about posting messages on the profiles.

Is there a way you can send one mass message to everyone on your friends list, or do you have to do one each individually? Just curious.

could be a wire shorting out
if it is running on all cyls and still does it it might be jetted to big on the main jets, or needs air filter/box work
